Add a lazy discovery interface for Unstructured

Delays the error until the first call and then preserves it for others.
More closely matches the intent of the Object() calls. Loaders are now
lazy and don't need to return errors directly.

Sets the stage for collapsing unstructured and structured builders
together.
